XAS Spectra of Synthesized Glasses bundle released

The XAS Spectra of Synthesized Glasses bundle has been released. These data have been added to the Spectral Library interface.

This database includes X-Ray Absorption Near-Edge Structure (XAS) spectral data from a PDART investigation of synthesized glasses (DOI 10.2138/am-2016-5555). In this investigation, multivariate techniques were used to enable accurate XAS measurements of Fe, Cr, Mn, and Ti ratios across the whole spectral region through creation of a broad suite of experimentally homogenized glasses of geological relevance for use as XAS standards. Iron, Cr, Mn, and Ti were analyzed as epoxy-mounted polished glass beads using XAS at the GeoSoilEnviroCARS beamline at the Advanced Photon Source, Argonne National Laboratory using a spot size of ca. 1x1 μm.
